| Apr 3, 2022 at 6:19 | comment | added | Denis Serre | The pullback operation applies to differential forms of various degrees $r$. When $r=0$, these are functions and the pullback is just the composition. When $r\ge N$, the pullback is the Jacobian of $\phi^0_t$, times this composition. | |
| Apr 2, 2022 at 21:09 | comment | added | Riku | Thank you. One more question: what is explicitly $(\phi^0_t)_\sharp u_0$ and how does it differ from $u_0\circ \phi_t^0$? | |

| Apr 1, 2022 at 12:42 | comment | added | Riku | I think I understand: so you're saying that the supremum change depends on the divergence of $a$ for the conservation law? | |
